Renewing a domain in redemption period

Hello,
I owned c100interns.com (purchased through wordpress) and it has expired. It states that it is currently in redemption period. I would like to redirect my blog back at that domain but am unable to do that.
How might I do so as promptly as possible?
In the mean time I've directed it at c100intern.com (note the singular intern vs. interns)

The domain c100interns.com expired on July 19 and is currently in redemption. This means that the domain is deactivated, but has not yet been fully released. During this time, you can still renew this domain, but the process is more complicated than a regular renewal.

I have sent you an email with further details. Please reply to the email when convenient.
